Q may Patented Mar. 18, 1930 PATENT OFFICE VINCENT TOIPE, OFSHARPSVILLE, PENNSYLVANIA INGOT-MOLD FLASK Application filed February25, 1929. Serial No. 342,360.

My invention relates to certain new and useful improvements in flasksfor casting ingot molds, and important objects of the invention are toprovide a flask of the character described, which will expedite ingotmold casting operations, which embodies novel means facilitating theremoval of the cast ingot mold therefrom, and which may be repeatedlyreused for ingot mold casting 10 operations.

Further objects of the invention are to provide a device of the classstated which is simple in its construction and arrangement, strong,durable and efficientin its use, and

15 comparatively inexpensive to manufacture,

maintain and operate.

With the foregoing and other objects in view which will appear as thedescription ro'ceeds, the invention resides in the comgo ination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the vention hereinafter disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawing wherein like, numerals of reference designatecorresponding parts throughout the several views ingot mold flaskconstructed in accordance with the invention.

Figure 2 is a top plan view thereof. Figure 3 is a sectional view online 3--3, Figure 2.

Figure 4 is a sectional view on line 44, Fi ure 2.

igure is a plan view of a clamp member. Figure 6 is an enlarged view ofthe releasable connecting bolts.

Figure 7 is an enlarged View of the gate block.

Referring in detail to the drawing 1 denotes the hollow body portion ofmy imroved flask which is vertically divided into our separatecomplemental quarter sections, respectivelyindicated at 2, 3, 4 and 5.The sections 2 and 3 are identical in construction and sections 4 and 5correspond in. construction.

Figure 1 is a side elevational view of an The periphery of each of thesections 2, 3, 4

5, is provided with three vertically disposed, integrally formed,re-enforcing ribs, respectively indicated at 6 and 7 and with fourhorizontally disposed, circumferentially extending, re-enforcing ribs,respectively indicated at 8, 9, 10 and 11, which are merged atintersections with the vertical ribs 6 and 7. The vertical ribs 6 ofeach of the sections 2, 3, 4 and 5 are disposed at respective sidesthereof, while the other vertical rib 7 is disposed centrally betweenthe associated ribs 6. A staple 12 is fixed adjacent to each end of theribs 7 to facilitate connections for handling independent sections 2, 3,4 and 5.

The adjacent ribs 6, of the sections 3 and 5, and of the sections 2 and4, are respectively joined together with a plurality of bolts 13, whichextend horizontally through registering apertures 6 provided therefor inopposed ribs 6 of the sections 3 and 5, and of the sections 2 and 4.

Each of the bolts 13 is secured in position by a fiat wedge 14, whichextends through a slot 15 formed adjacent to one end of the bolt 13. Aretaining bolt 16 extends through the lower narrow end of each of thewedges 14, to prevent the latters dis-engagement from its bolt slot 15unless desired.

the sections 4 and 5, securely together; The

opposed sides of associated ribs 6 are respectively provided with dowelsand with corresponding apertures 31 to facilitate the positioning of thesections 2, 3, 4 and 5, relatively to each other.

When the bolts 13 are secured in the adjacent ribs 6 of the sections 3and 5, and in the opposed ribs 6 of the sections 2 and 4, and when theclamps 17 are in their securing positions on the adjacent ribs 6 of thesections 2 and 3 and on the opposed ribs 6 of the sec-- tions 4 and 5,in the manner stated, all of the sections 2, 3, 4 and 5 are properlyjoined together to constitute the flask body portion 1 having a largevertically extending flask opening 18, which is open at both ends andgradually and slightly increasing in area from its upper to its lowerend.

The sections 2 and 3 are formed to combinedly form a verticallyextending, laterally disposed, offset ortion 19, in which the verticallyextending pouring gate 20is provi'ded. The lower end of the lattercommunicates with a horizontally extending recess 21, which is disposedadjacent to the lower end of the body portion 1 and communicates withthe flask opening 18.

The recess 21 is adapted for the reception of a replaceable refractorygate block 22. The latter is formed with a passage 23 which communicateswith the flask opening 18 and. the vertical pouring gate20.

When preparing my improved flask for pouring the metal, a gate stick 24is positioned centrally in the pouring gate 20 with the lower endthereof inserted in the communicatin end of the block passage 23.Suitable sand is then tamped around the gate stick 24 and the latterwithdrawn leav ing a continuous pouring passage through the tamped sandwhich communicates with flask opening 18, through theinter-communicating block passage 23. By this construction the metal,during the pouring operation, Will never contact with ordamage thepouring gate 20 and block recess 21. ()f course, before each castingoperation it will be necessary to resand the pouring gate 20' and toreplace the gate block 22. The pouring gate 20 is further provided witha plurality of vents 25 to dissipate potential gases created during thepouring operation, which would otherwise tend to disrupt the sandstructure in the pouring gate 20.

A pair of opposed recesses 26 are formed at the upper end of the innerperiphery of the body portion 1. Each of the recesses 26 is combinedlyformed between respective adj acent sections 2 and 4 and the sections 3and 5. The recesses 26 provide for casting correspondingly shaped lugsupon the ingot mold being cast, to facilitate its handling.

The handling of the ingot mold being cast is further provided for bycombinedly forming another recess 27 between the sections 2 and 4. Alifting loop 28 is adapted for being properly sanded in the recesses 27,so that the free ends of the former are integrally em? bedded in theingot mold, being cast, during the casting operation.

Another recess 29 is combinedly formed between these same sections 2and4. The recess 29 is comparatively shallow and is intended to beproperly sanded to receive a suitabie impress providing identifyingcharacteristics on the ingot mold being cast.

All surfaces of the body portion 1, including the surface of the flaskopening 18, are properly sanded before each casting operation, so thatthe damage to the flask is reduced to a minimum, thereby permitting ofthe use of the same flask for repeated casting operations;

During ingot mold casting operations, the usual sanded core bar, (notshown) is, of course, positioned in the flask opening 18, so that theingot mold casting acquires the conformation of an ingotmold ofregulation configuration.

In releasing the cast ingot mold from my 1mproved flask, the wedges 14are driven up wardly to slightly release the bolts 13, and t clamps 17are removed entirely. Such release of the bolts 13 willallow a slightdisengagement of the connection of the sections 2 to 4, and 3 to 5,while the removal of the clamps 17 will permit of the parting of theconnections of the sections 2 to 3 and 4 to 5. The release of thesections 2, 3, 4 and 5, in the manner stated, will facilitate andexpedite the removal of the cast ingot mold from the flask body portion1.

The present invention provides a most efflcient flask for facilitatingand expediting ingot mold castin operations in an economic manner.
